| dc.description.abstract | The universal criterion for ultrafast vortex-core switching between the up- and down-core bistates in soft magnetic nanodots is investigated by micromagnetic simulations along with vortex-core switching that occurs whenever the velocity of vortex-core motion reaches its critical velocity, υcri=(1.66±0.18)γAex (e.g., υcri=330±37m/s for Permalloy), with the exchange stiffness Aex and the gyromagnetic ratio γ. On the basis of the universality of υcri, phase diagrams for the vortex-core switching event and switching time with respect to both the amplitude and frequency of a circularly rotating magnetic field are calculated. | - |
